Description

Technical Field

[0001] The utility model relates to the technical field of glass cleaning, in particular to a cleaning device and a screen printing device. Background Art

[0002] Glass silk screen printing is a process in glass processing that involves screen printing on the glass surface. Ink is applied to the glass using a specific process, followed by heat treatment and curing to ensure the printed pattern or text is more durable and resists fading. However, existing production lines require glass to be cleaned in a cleaning machine before entering the screen printing room for screen printing. To avoid line downtime and disrupt production, and to ensure accurate positioning of the glass as it enters the equipment, a glass storage device and glass positioning devices are required between the roller conveyor connecting the cleaning machine and the screen printing room entrance. This results in a longer roller conveyor between the cleaning machine and the screen printing room. In some areas, seasonal changes increase the number of flying insects. Even after cleaning, flying insects can still land on the glass before it enters the screen printing room. This insect-laden glass entering the screen printing room for screen printing not only results in printing defects, compromises the quality of the printed glass, and results in glass waste. Furthermore, the presence of flying insects and other impurities on the glass during screen printing can cause friction and impact with the screen, reducing the durability of the screen. How to reduce the amount of impurities that enter the screen printing room and improve the yield rate is a problem that needs to be solved urgently. Although the existing technology can provide an air knife to clean the glass on the conveyor belt, the air knife in the existing technology, such as the Chinese patent application (CN214892325U), provides a quick cleaning device, in which the air knife body is provided with two air guide plates that fit with the front and rear side walls of the air knife body, and the front and rear side walls of the air knife body are both provided with two slides that match the air guide plates. The slide is provided with a first bolt connected to the air guide plate. By sliding the first bolt up and down in the slide, the first bolt drives the air guide plate to move, and then the air guide plate is fixed by screwing the first bolt, so that the width of the air outlet is adjusted by the two air guide plates. Although the air outlet width of the air knife in this patent application is adjustable, it is necessary to adjust the air guide plates on both sides separately. The air outlet width of the air knife is difficult to adjust and the air outlet pressure is difficult to control. Summary of the Invention

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The purpose of the utility model is to provide a cleaning device and a screen printing device to solve the problems existing in the prior art, so that the air outlet width of the cleaning device can be easily adjusted and the air outlet pressure can be easily controlled.

[0027] In order to make the above-mentioned purpose, features and advantages of the present invention more obvious and easy to understand, the following is a brief description of the present invention in conjunction with the attached Figures 1 to 6 The present invention is further described in detail with reference to the accompanying drawings and specific implementation methods.

[0028] Example 1

[0029] This embodiment provides a cleaning device, including: a cutter body 1 and a rotating shaft 3.

[0030] refer to Figures 1 to 3 The blade body 1 has a cavity for air circulation within it. The blade body 1 is provided with an air inlet 7 and multiple air outlets 2. The air inlet 7 is used to connect to an air supply device. The air outlets 2 and the air inlet 7 are both connected to the cavity, and the air outlet widths of the air outlets 2 vary. A rotating shaft 3 is fixedly connected to the blade body 1, and the multiple air outlets 2 are distributed around the axis of the rotating shaft 3. The cleaning device provided by the utility model can easily adjust the air outlet width of the cleaning device by rotating the blade body 1 and replacing the air outlet 2. The air outlet pressure is also easily controlled, making it flexible and suitable for cleaning different types of glass. Different air outlets 2 can be used for cleaning according to the type of glass, ensuring the cleanliness of the glass before entering the screen printing room, reducing glass loss, and improving the durability of the screen printing screen. Glass with a relatively flat surface requires a lower air pressure to ensure cleanliness, so an air outlet 2 with a larger air outlet width can be used. Glass with an uneven surface, on the other hand, requires a higher air pressure to ensure cleanliness, so an air outlet 2 with a smaller air outlet width needs to be replaced. Moreover, when the blower power is the same, the air outlet pressure can be increased by replacing the air outlet 2 with a smaller width. Compared with the method of adjusting the air outlet pressure by replacing a blower with a larger power, the cleaning device provided by the utility model can also reduce energy loss.

[0031] In some embodiments provided herein, the blade body 1 is prismatic, and the air outlet 2 is disposed on an edge of the blade body 1. This configuration of the blade body 1 being prismatic and the air outlet 2 disposed on an edge makes the air outlet 2 easier to manufacture and the air outlet angle easier to control. In this embodiment, the blade body 1 is a regular triangular prism, but the blade body 1 can also be a regular quadrangular prism, or other shape where the air outlet 2 is easily disposed.

[0032] In some embodiments provided by the present invention, reference is made to Figure 4 A plurality of ventilation cavities 4 are further provided inside the cavity. Each air outlet 2 is correspondingly provided with and connected to a ventilation cavity 4, and each ventilation cavity 4 is provided with an air inlet 7. The provision of a ventilation cavity 4 corresponding to each air outlet 2 avoids the need to seal unused air outlets 2 when multiple air outlets 2 share the same air duct, making it more convenient for operators to replace air outlets 2.

[0033] In some embodiments provided by the present invention, a baffle 8 is provided between two adjacent side walls in the cavity, and the baffle 8, the two end faces of the blade body 1, and the two side walls connected to the baffle 8 enclose a ventilation cavity 4. By fixing the baffle 8 on the two side walls to provide the ventilation cavity 4, the structure is simple and easy to process. In the present invention, the baffle 8 is a rectangular plate. In some other embodiments, the baffle 8 can also be other structures that can enclose the ventilation cavity 4. In this embodiment, the air inlet 7 is provided on the end face of the blade body 1, within the area enclosed by the two side walls connected to the baffle 8 and the baffle 8. In some other embodiments, the air inlet 7 can also be provided at other locations that are convenient for supplying air to the interior of the ventilation cavity 4.

[0034] In some embodiments provided by the present invention, reference is made to Figures 5-6 The cleaning device further includes a baffle 5, which is disposed at the air outlet 2 and is detachably connected to the blade body 1. The baffle 5 can partially block the air outlet 2 to adjust the air outlet length of the air outlet 2. Each air outlet 2 is provided with at least one baffle 5. The cleaning device of the present invention can adjust the air outlet length through the baffle 5, and the air outlet length can be adapted to different sizes of glass, thereby preventing the air outlet 2 from being too long and blowing foreign matter on the conveying device onto the glass surface, causing secondary contamination.

[0035] In some embodiments provided by the present invention, the baffle 5 is slidably connected to the air outlet 2, and the sliding baffle 5 can change the length of the air outlet 2 covered by the baffle 5. The air outlet length can be adjusted simply and conveniently by sliding the baffle 5. In this embodiment, grooves are provided on both sides of the air outlet 2 to cooperate with the baffle 5 to achieve a sliding connection between the baffle 5 and the air outlet 2. In some other embodiments, baffles 5 of different lengths can also be provided, and the air outlet length of the air outlet 2 can be adjusted by replacing and fixing the baffle 5. The baffle 5 can also be matched with the air outlet 2 by other fixing methods, for example, the rubber baffle 5 is fixed to the protruding nails on both sides of the air outlet 2 by a hanging strap.

[0036] In some embodiments provided by the present invention, reference is made to Figure 6 A seal 6 is provided inside the baffle 5. The seal 6 is provided at the position corresponding to the air outlet 2. The seal 6 can block the air outlet 2 and seal the space between the blade body 1 and the baffle 5. By blocking the air outlet 2 and the space between the blade body 1 and the baffle 5 by the seal 6, air leakage from the blocked portion of the air outlet 2 can be prevented, resulting in reduced air pressure and energy waste.

[0037] In some embodiments provided by the present invention, the inner side of the baffle 5 is aligned with the two sidewalls of the edge where the air outlet 2 is located, and an angle is formed where the inner side of the baffle 5 contacts the air outlet 2. The seal 6 is located at the angle. The baffle 5 of the present invention is aligned with the two sidewalls of the edge where the air outlet 2 is located, which reduces the material consumption and has a simple structure and is easy to process. In addition, the seal 6 is located at the angle and can be fixed at the angle by means of bonding or other methods, which makes it firmly fixed and not easy to fall off. In other embodiments, the baffle 5 can also be configured into other shapes that can seal the air outlet 2.

[0038] In some embodiments of the present invention, each air outlet 2 is provided with two stoppers 5, which are respectively connected to and block the two ends of the length direction of each air outlet 2. The stoppers 5 are provided on both sides of the air outlet 2. When the glass is at the center of the conveying device, the air outlet length of the air outlet 2 is prevented from being adjusted to the length of the glass by moving the blade 1. The effective air outlet position of the air outlet 2 is simple and easy to adjust.

[0039] In some other embodiments, an angle mark is further provided on the rotating shaft 3, and the angle mark is used to assist in adjusting the air outlet angle of the blade body 1, so as to facilitate the operator to adjust the angle and control the air outlet angle of the cleaning device.

[0040] Example 2

[0041] This embodiment provides a screen printing device, including a screen printing room, a conveying device and a cleaning device. The screen printing room is used to screen print glass, and the screen printing room has a glass entrance; the conveying device is used to input glass into the screen printing room through the glass entrance; the cleaning device is arranged on the outside of the glass entrance, and the air outlet can blow air to clean the glass on the conveying device.

[0042] In some other embodiments, the cleaning device can be arranged above the conveying device via a bracket, and the rotating shaft 3 can be rotatably connected to the bracket, which is convenient to adjust and easy to implement. In some other embodiments, the rotating shaft 3 can also be supported and clamped by a clamping structure. By loosening the clamping structure, the air outlet 2 and the air outlet angle of the blade body 1 can be adjusted. The operation is convenient and can clean glass of different sizes and types. It has a wide range of applications. In addition, by rotating the blade body 1, the air outlet 2 with different air outlet widths can be selected to adjust the air outlet pressure. Compared with the method of adjusting the air outlet pressure by replacing a more powerful blower, the screen printing device provided by the utility model can also reduce energy loss and save the cost of glass cleaning. In addition, glass with flying insects entering the screen printing room for screen printing will not only cause printing defects and waste glass, but also the presence of flying insects and other impurities on the glass during screen printing will cause squeezing and friction with the screen printing plate, which will also reduce the durability of the screen printing plate. A cleaning device is installed outside the glass entrance of the screen printing room to clean the glass surface, preventing glass with impurities from entering the screen printing room, improving the yield of glass screen printing, reducing glass loss, and enhancing the durability of the screen printing screen. In other embodiments, a dust cover is also installed at the glass entrance. The projection of the dust cover on the conveyor device can completely cover the cleaning device and the glass entrance, preventing the cleaned glass from being contaminated by impurities such as fallen insects.

[0043] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
